  • Gigabit Switch PoE Principle

    Gigabit Switch PoE Principle

    The answer is through the use of phantom power—power sent over the same wire pairs used for data. When the same pair is used for both power and data, the power and data transmissions don't interfere with each other. This allows a single cable to provide both a data connection and enough electricity to power networked devices such as wireless access points. A PoE (Power over Ethernet) switch is a network switch that delivers both power and data through a single Ethernet cable to connected devices such as IP cameras, VoIP phones, wireless access points, and IoT devices. A PoE switch is a network switch that has PoE injection built-in, eliminating the need for separate power supplies for network devices.
